In August, milkweed seed pods are often covered by a collection of little orange and black bugs. These are the nymph of the Milkweed Bug. This is normally the second or third generation for the year.

Adult females deposit their eggs between the crevices between milkweed seed pods and also on the outside of the pods. It takes 4-6 days for the eggs to hatch and the tiny nymphs emerge. Over a month’s time, the nymphs will molt going through 5 instar phases before becoming adults.

Like the Monarch Butterfly, they avoid predators by feeding on milkweed, becoming too bitter and toxic to be eaten.

Best Way To Contain Them In Your Garden
